SAIL.

SPECIFICATION forming part of Letters Patent No. 721,286, dated February24, 1903.

Application filed December 15, 1902. Serial-No. 135,358-. (No model.)

To all whom it may concern.

Be it known that I, JOEL COUCH, a citizen of the United States, residingat Clayton, in

the county of Jefferson and State of New York, have invented certain newand useful Improvements in Sails; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame,reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in sails forboats; and it consists in the provision of a series of sections whichare connected together and having corresponding endsleft free or open'and somewhat baggy to give the sail more driving power and in theprovision of springs or other elastic material connecting the gaff withthe mast, whereby the former may be allowed to sway when a strong pufiof wind strikes the sail, thereby relieving the sail and holding samefirmly against the wind.

The invention consists, further, in the provision of a sectional sailconnectedtoa boom, mast, and gafi, said boom being hinged to a yokesecured to the mast, whereby the boom and mast are caused to rotatetogether or rock' on the lower pivotal end of the mast.

The invention consists,further,in the novel construction, combination,and adaptation of parts, as will be hereinafter more fully described indetail and then illustrated inthe accompanying drawings.

My invention is clearly illustrated in the accompanying drawings, inwhich- V Figure l is a perspective view of my improved sail; and Fig. 2is a cross-section of a mast, showing boom connection in plan.

Reference now being had to the details of the drawings by letter, Adesignates the mast of the sail, having a pivotal pin A at its lowerend, and A is a band or yoke which passes about the mast and is securelyfastened thereto by means of a bolt a. The boom B is pivotally mountedona pin B,'which is held in.

apertures in the ends of said 'yoke, as shown.

The sail proper is made up of a series of sections 0, which areconnected at corresponding ends to vertically-disposed ropes or tapes D,which extend between the gaff and boom. each section of the sail areconnected to the The opposite longitudinal edges of intermediate thefree end of the section and the adjacent end of another section, whichis fastened to a rope or tape D. Each free end of a sail-section is leftbaggy, as illustrated,

-in order to give more drive or push to the sailfthe open spaces betweenthe sections being provided for the purpose of allowing the sail to beinstantly relieved of dead wind. v

Fastened to the cross-bar L, which is supported by the mast, are thesprings N, connected at corresponding ends to the gaff at points N.These springs are provided for the purpose of allowing the sail to giveslightly under excessive pressure and to hold the sail against the wind.From the foregoing it will be observed tha by the provision of a sailmade in accordance with my invention the sections will be relievedinstantly of deadwind and the sail will move with the mast, the gafiallowed to yield, and same kept parallel under normal conditions withthe boom. A sail as described is moredurahle than the ordinary sail madeup of a single piece of canvas and has more driving-power, as the freeends of the sections being wider than their other ends will sag when thewind strikes same.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

1. A sail made up of a series of sections, each of which has a freebaggy edge intersecting pockets to which the fixed edges of the sectionsare connected, a rotatable mast, a boom to which said sail-sections areconnected, and which boom is mounted to move with the mast, as setforth.

2. A sail made up of a series of sections, each of which has a free edgewhich is wider than its opposite fixed end,.a rotatable mast, a yokesecured thereto, and a boom to which said sail-sections are connected,said boom a gaff having yielding connections with said the mast, a gaff,and springs connecting same mast, as set forth. with said cross-piece,as set forth. in 3. A sail made up of a series of sections In testimonywhereof I hereunto aifix my each section having a corresponding freesignature in presence of two witnesses.
